Subject Kinematics and Experimental Paradigm.

<p>(A) Shows the weights given to each of the three dimensions (height, depth, and lateral) when computing the first PC of the movement kinematics. Each point represents the PC weight calculated using a different cross-validation. (B–D) Show different views of the experimental paradigm and example kinematics from one of the subjects' sessions. The red dashed line represents the first PC plotted in Cartesian space for that same session.
